Rheumatic Heart Disease
Rheumatic Heart Disease samer kareem 4,564 Views • 2 years ago

Rheumatic heart disease (RHD) is the most common acquired heart disease in children in many countries of the world, especially in developing countries. The global burden of disease caused by rheumatic fever currently falls disproportionately on children living in the developing world, especially where poverty is widespread. RHD is a chronic heart condition caused by rheumatic fever that can be prevented and controlled. Rheumatic fever is caused by a preceding group A streptococcal (strep) infection. Treating strep throat with antibiotics can prevent rheumatic fever. Moreover, regular antibiotics (usually monthly injections) can prevent patients with rheumatic fever from contracting further strep infections and causing progression of valve damage. Consequences of rheumatic heart disease Acute rheumatic fever primarily affects the heart, joints and central nervous system. The major importance of acute rheumatic fever is its ability to cause fibrosis of heart valves, leading to crippling valvular heart disease, heart failure and death. The decline of rheumatic fever in developed countries is believed to be the result of improved living conditions and availability of antibiotics for treatment of group A streptococcal infection. Overcrowding, poor housing conditions, undernutrition and lack of access to healthcare play a role in the persistence of this disease in developing countries.

Bone Tumor. Reasons
Bone Tumor. Reasons samer kareem 5,792 Views • 2 years ago

Bone tumors develop when cells in the bone divide without control, forming a mass of tissue. Most bone tumors are benign, which means they are not cancer and cannot spread. However, they may still weaken bone and lead to fractures or cause other problems. Bone cancer destroys normal bone tissue and may spread to other parts of the body (called metastasis). Benign Bone Tumors Benign tumors are more common than malignant tumors of the bones. These are a few common types of benign bone tumors: Osteochondroma is the most common benign bone tumor. It is more common in people under age 20. Giant cell tumor is a benign tumor, typically affecting the leg (malignant types of this tumor are uncommon). Osteoid osteoma is a bone tumor, often occurring in long bones, that occurs commonly in the early 20s. Osteoblastoma is a single tumor that occurs in the spine and long bones, mostly in young adults. Enchondroma usually appears in bones of the hand and feet. It often has no symptoms. It is the most common type of hand tumor.

Nelson's syndrome
Nelson's syndrome samer kareem 4,817 Views • 2 years ago

Nelson syndrome refers to a spectrum of symptoms and signs arising from an adrenocorticotropin (ACTH)–secreting pituitary macroadenoma after a therapeutic bilateral adrenalectomy. The spectrum of clinical features observed relates to the local effects of the tumor on surrounding structures, the secondary loss of other pituitary hormones, and the effects of the high serum concentrations of ACTH on the skin. [1] The first case was reported by Nelson et al in 1958. [2]

How Does Diabetes Cause Silent Heart Attacks?
How Does Diabetes Cause Silent Heart Attacks? samer kareem 6,142 Views • 2 years ago

A silent heart attack is a heart attack that has few, if any, symptoms. You may have never had any symptoms to warn you that you've developed a heart problem, such as chest pain or shortness of breath. Having diabetes or prediabetes puts you at increased risk for heart disease and stroke. You can lower your risk by keeping your blood glucose (also called blood sugar), blood pressure, and blood cholesterol close to the recommended target numbersthe levels suggested by diabetes experts for good health.

ABSTRACT
Minimal invasive laparoscopic cholecystectomy is the typical surgical treatment for cholelithiasis (gallstones), where patients present with a history of upper abdominal pain and episodes of biliary colic. The classic technique for minimal invasive laparoscopic cholecystectomy involves four ports: one umbilicus port, two subcostal ports, and a single epigastric port. The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) has instituted a six-step strategy to foster a universal culture of safety for cholecystectomy and minimize risk of bile duct injury. The technical steps are documented within the context of the surgical video for (1) achieving a critical view of safety for identification of the cystic duct and artery, (2) intraoperative time-out prior to management of the ductal structures, (3) recognizing the zone of significant risk of injury, and (4) routine intraoperative cholangiography for imaging of the biliary tree. In this case, the patient presented with symptomatic biliary colic due to a gallstone seen on the ultrasound in the gallbladder. The patient was managed a mini-laparoscopic cholecystectomy using 3mm ports for the epigastric and subcostal port sites with intraoperative fluoroscopic cholangiogram. Specifically, the senior author encountered a tight cystic duct preventing the insertion of the cholangiocatheter and the surgical video describes how the author managed the cystic duct for achieving a cholangiogram, in addition to the entire technical details of laparoscopic cholecystectomy.

Direct Laryngoscopy
Direct Laryngoscopy samer kareem 7,403 Views • 2 years ago

Visualization of the larynx by direct or indirect means is referred to as laryngoscopy and is the principal aim during airway management for passage of a tracheal tube. This paper presents a brief background regarding the development and practice of laryngoscopy and examines the equipment and techniques for both direct and indirect methods. Patient evaluation during the airway examination is discussed, as are predictors for difficult intubation. Laryngoscope blade design, newer intubating techniques, and a variety of indirect laryngoscopic technologies are reviewed, as is the learning curve for these techniques and devices.
